Abstract: This work concerns the temporal and spatial analysis of daily and extreme events of rainfall in North-Eastern Algeria. The trend of ten indices of precipitation extremes in 16 meteorological stations have been analysed using the innovative approach with a period between 1970 to 2008. This method is based on visual analysis of trend and contrary to other classical approach, not requires restrictive assumptions for its application. The indices used in this study concern the intensity, duration and frequency of rainfall events. The major results of this work concern the increase of extreme rainfall events in many parts of the target area and an opposite tendency for dry spells. These facts lead to suppose a better situation in terms of water resources but an aggravation of the flood situation, which is known this part of the country.
